Important things to remember about Face Unlock

Never use Face Unlock while driving. This is very obvious. When driving, you should be focused on the road and not on your phone so do not unlock your phone using Face Unlock while driving. The unlocking process requires you to look at the screen to align what the camera is catching; this may distract you from traffic and may create unnecessary damages and injuries.

Security level of Face Unlock is low. Face Unlock is considered by Samsung as one of the locks that has the lowest level of security. This is because someone who looks like you, or brings a picture of you can easily unlock your phone and have the data to it. As much possible, when using Face Unlock, keep your important data safe by using other securing methods and applications.

A person who looks like you could unlock your device using Face Unlock. As mentioned above, anyone who looks like you (e.g., a brother, sister or twin) could possibly unlock your phone and have access to its important data.

Do not forget the backup PIN or Pattern Lock. You may not realize it yet but making sure you remember you pre-set PIN or pattern lock to unlock a device that does not detect the face. In cases that you are on a dimly lit place or your phone does not recognize your face, log in back to your phone by entering the correct pattern or PIN.
